We managed to get to the place using Google Maps and Grab taxi. Grab (or walking and then using the subway) is also the only way to leave, there are no meter taxis or tuctucs available. Getting to the subway and from there to town was easy but a bit to me consuming.
The check-in is easy, you just get the key from a lady downstairs. The neighborhood is nice and quiet and not touristic at all, so you get to experience authentic Thai living.
The room is basic but comfortable and good value for money.
